New stars like our Sun

NASA researchers estimate that there are billions of yellow, dwarf-like stars in the Milky Way in the Milky Way, and that more than half of them could host at least one exoplanet in their habitable zones.

It should be noted that this estimate is not a guarantee that any of these exoplanets are or have ever been habitable. But the study by NASA scientists provides the most accurate balance of the number of planets in the galaxy that, at least in theory, could meet the requirements for hosting life.

Experts explain that there are many factors to consider when a study tries to determine the "habitable zone" of a star. The most important of these are: the distance between the star and the surrounding planets and the temperatures felt at the surface of the planets.

According to Futurism, the new study did not consider any of them, but only calculated how many Sun-like stars an exoplanet could have, in what could be a reasonable approximation of a habitable zone. This approximation of the limits of the habitable area was obtained by compiling the data obtained from previous studies.

Based on a series of data and assumptions about the stars and solar systems in the Milky Way, scientists have concluded that, on average, there are between 0.37 to 0.60 exoplanets in a habitable zone and 0.58 up to 0.88 exoplanets in a wider and harder area, but with habitable potential.

New informations about the Dead Sea Scrolls

The famous Dead Sea Scrolls continue to generate riddles, decades after their discovery. A recent study concluded that at least one different technique was used to obtain one of them than the rest, an unknown technique, unheard of to this day. The parchment that attracted the attention of researchers, one of the most important in the collection, is one with an age of almost 2.000 years, which has been remarkably well preserved, despite the conditions in which it was kept and despite its size. of the largest. Found by the Bedouins in 1956, north of the Dead Sea, it was sold to an antique dealer. He did not keep it in the best conditions, but still wrapped it in cellophane and stored it in a shoe box, hidden under the floor, according to Science Alert. The "Temple Parchment", as he is known, has survived, but is currently the thinnest of the parchments (a collection of about 900 pieces). It is only one tenth of a millimeter thick. However, it was preserved, and the material ...

Hundreds of metal spheres under pyramid in Mexico

Archaeologists have discovered hundreds of metal spheres buried under an ancient pyramid near Mexico City. Scientists have no idea what the mysterious balls were for. Jorge Zavala, an archaeologist at the National Institute of Anthropology and History in Mexico, described the discovery as "unprecedented." The spheres have been hidden for the last 1800 years in one of the most important pre-Hispanic temples in Mexico City, writes gizmodo.com. The city of Teotihuacan, just 45 kilometers from Mexico City, was once one of the largest cities in the world, with more than 100,000 inhabitants, at a time when only 200 million people lived on Earth. Its massive population makes it even more mysterious the total abandonment of the city in the year 700 of our era. The people of Teotihuacan knew very well that they would never return to the city, so before fleeing from it, they filled their much-loved temples with waste and garbage. Their level was so high that it took scientists only a f...

Oldest writing in the world

"The Danube Valley civilization is one of the oldest known civilizations in Europe. A German scientist, Harald Haarmann, claims that the oldest writing in the world appears on tablets discovered at Tartaria, in Romania. The tablets discovered in Romania are dated around 5,500 BC, and the symbols on them, according to the German linguist Harald Haarmann, belong to an ancient language, which has not yet been deciphered, according to Ancient Origins. These signs, which are called Vinca symbols, were found in several archeological sites, along the regions of the Danube Valley, they being inscribed on ceramics, figurines and other clay artifacts from that period. While some archaeologists believe that this writing represents only a series of geometric figures and symbols, others have argued that the sequence of symbols is the oldest writing ever discovered, it predates the Sumerian Mesopotamian and even the tablet Dispilio, which was dated. from the year 5,260 BC. The implications of...
